Image quality scores—presence of artifact. LM = left main coronary artery; RCA = right coronary artery; MPA = main pulmonary artery; RPV = right‐sided pulmonary veins; LPV = left‐sided pulmonary veins. Two blinded reviewers (R1, R2) assessed the clinical sequence (T2 prepared 3D whole heart) and MTC‐BOOST bright blood datasets to grade presence of artifact (1 = severe artifact, 2 = significant artifact, 3 = moderate artifact, 4 = mild artifact, and 5 = minimal artifact) where grades 1 and 2 delineate nondiagnostic datasets. For each observer, the scores were compared using a paired Wilcoxon signed‐rank test, with statistical significance difference set to P < 0.05.
